Hidden Operating System


If your system partition or system drive is encrypted using TrueCrypt, you need to enter your pre-boot authentication password in the TrueCrypt Boot Loader screen after you turn on or restart your computer. It may happen that you are forced by somebody to decrypt the operating system or to reveal the pre-boot authentication password. There are many situations where you cannot refuse to do so (for example, due to extortion). TrueCrypt allows you to create a hidden operating system whose existence should be impossible to prove (provided that certain guidelines are followed — see below). Thus, you will not have to decrypt or reveal the password for the hidden operating system.

Google Search Tricks and Tips


A large number of people use google to search content which they like.Google is surely leading search engine so it will be good that i share with my readers on how to search more exactly and easily what they want.All i got this by experience and a bit surfing and i will try to sum up all thins here.

1.Find specific URL:
Inorder to find specific url containing something like /portals/0 or anything like call/index.php. Then we shall use a google dork like
inurl:'term to search'   e-g  inurl:'/portals/0'  and you will get results in no time.
2.Limit searches to a particular site:
I use this one all the time, and it’s particularly handy because many site’s built-in search tools don’t return the results you’re looking for (and some sites don’t even have a search feature). If i am looking for movies songs in site songs.pk then i will try:
movie name site:songs.pk    or simple i may say      content type site: any.com
3.Use of OR:
Putiing capital OR in between terms will search both the terms, either that term or the other.
Like:
ipod OR mp3 player
4.Use of related:
Including related: and the  URL searches for the results that are somehow related to that URL.like
related:google.com
5.Use of ~ :
Putting text a~ infront of a word searches for a word but also for its synonyms. e-g searching for cat~nutrition will give you result of nutrition and food,protein etc, so we can use:
text~function
6.Use Google as a calculator:
Google has a built-in calculator — try entering a calculation like 110 * (654/8 + 3). Yes, your computer also has a calculator, but if you spend most of your day inside a browser, typing your calculation into the browser’s search box is quicker than firing up your calculator app.

7.Get quick currency conversions:
Google can also do currency conversion, for example: 100 pounds in dollars.
(Note: there are many online sites for doing this in more authentic way.)

8.Search for specific document types:
Google can search the web for specific types of files using the “filetype:” operator. If you’re looking for PowerPoint files about hackersthirst, for example, you could try:
hackersthirst filetype:ppt
9.Search within numerical ranges using the .. operator:
Say, for example, you want to look for information about Olympic events that took place in the 1950′s, you could use this search:
 Olympics 1950..1960
10.Area code lookup:
Need to know where a phone number is located? Google will let you know where it is, and show you a map of the area, too. For example type this and search:
415
11.Phone Listing:
Let’s say someone calls you on your mobile number and you don’t know how it is.  If all you have is a phone number, you can look it up on Google using the phonebook feature thats so simple but the number must be in :P.
Example:
phonebook:617-555-1212 (note:  the provided number does not work – you’ll have to use a real number to get any results).
12.Word Definitions:
If you need to quickly look up the definition of a word or phrase, simply use the "define:" command.
Example: define:hacking
So, guys which one is your favourite search type.

Keep Your Passwords Safe


What is KeePass?
 Today you need to remember many passwords. You need a password for the Windows network logon, your e-mail account, your website's FTP password, online passwords (like website member account), etc. etc. etc. The list is endless. Also, you should use different passwords for each account. Because if you use only one password everywhere and someone gets this password you have a problem... A serious problem. The thief would have access to your e-mail account, website, etc. Unimaginable.

 KeePass is a free open source password manager, which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key file. So you only have to remember one single master password or select the key file to unlock the whole database. The databases are encrypted using the best and most secure encryption algorithms currently known (AES and Twofish).

Features
  • Strong Security
  • Multiple User Keys
  • Portable and No Installation Required
  • Export To TXT, HTML, XML and CSV Files
  • Import From Many File Formats
  • Easy Database Transfer
  • Support of Password Groups
  • Time Fields and Entry Attachments
  • Auto-Type, Global Auto-Type Hot Key and Drag&Drop
  • Intuitive and Secure Clipboard Handling
  • Searching and Sorting
  • Multi-Language Support
  • Strong Random Password Generator
  • Plugin Architecture
  • Open Source!

For more information, see the features page.


Is it really free?
 Yes, KeePass is really free, and more than that: it is open source (OSI certified). You can have a look at its full source and check whether the encryption algorithms are implemented correctly.

Test Your Anti-Virus


You can also test your anti virus program for its effectiveness using a simple notepad trick. Follow the steps below to know more:
Open Notepad.
Copy the code give below in the notepad file:
X5O!P%@AP[4PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*
Save it with an .exe extension like testvirus.exe
As soon as you save this file, your anti virus program will detect the file (virus) immediately and will attempt to delete it. If this happens then your Antivirus is working properly. If not, then its time to look for some other reliable program.

NOTE: The EICAR test file (#3) is a 16-bit application and cannot be run on 64-bit versions of Windows.

Make the Matrix


To make this, open notepad and type the following:
@echo off
 color 2
 :start
 echo %random% %random% %random% %random% %random% %random% %random% %random% %random% %random% %random% %random% %random% %random%
 goto start

Save this file as Matrix.bat
 Make sure the file type is kept as ALL FILES while saving it as a .bat file.

Open the saved file and see the magic.
